The effect of different substrates and foliar spraying of seaweed extract on growth, yield and nutrient content of Karla (Momordica Charantia L.)

  This research was carried out to investigate the effect of different substrate and spraying of seaweed extract on growth, yield and nutrient content of karla .

this research was carried out in a factorial design based on completely randomized design with four replicate in pots under hydropnic condition in rUniversity of Researcher Ardabil University. The first factor includes combination of substrate 50: 50 ratios (100) ratios (sawdust + cocopes, sawdust + perlite, sawdust + vermiculite, perlite + cocopeat, cocopeat + vermiculite, vermiculite + perlite) and second factor of leaf spray with Ascophyllum nodosum seaweed extract in four Concentration (0, 0.5, 1 and 2 grams per liter) and in control treatment was sprayed with distilled water.

The results showed that the highest amount for plant height (3.79 m) in vermiculite-cocopeat substrate and seaweed extract concentration of 1 g / l and the highest value for plant fresh weight plants (575.49 grams), dry weight (27.29 g), root fresh weight (149 / 81 g) and fruit yield (1492/50 g) were obtained in vermiculite-perlite treatment with a concentration of seaweed extract of 1 g / l, also in plant dry weight traits (138.36 g), fresh weight of fruit (33.36 g) In combination of vermiculite-perlite substrate and foliar spraying of 2 g / l from seaweed extract and .

 the results of this study indicated that the use of seaweed extract and perlite-vermiculite had the greatest impact on growth of karla in comparison to other treatments
